Detailed Description

In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below with reference to the accompanying drawings and examples.

The sawing and cooling device for the large-diameter titanium ingot forgings shown by referring to figures 1-7 comprises a cooling main pipe 1 arranged on a sawing machine, wherein the cooling main pipe can be communicated with a cooling liquid pipe of the sawing machine body, and the cooling liquid pipe continuously outputs cooling liquid into the cooling main pipe 1 through a cooling liquid pump of the sawing machine.

The cooling tube 2 adapting to the radian of the outer peripheral surface of the titanium ingot is communicated with the bottom end of the cooling main tube 1, cooling holes 2a are formed in the peripheral surface of the cooling tube 2 at intervals along the circumferential direction, the cooling tube 2 is manufactured into a structure parallel to the peripheral surface of the sawed titanium ingot, cooling liquid in the cooling main tube 1 can sufficiently cool the peripheral surface of the whole titanium ingot sawed through the cooling holes 2a formed in the intervals on the cooling tube 2, as shown in fig. 4, the problems that pipelines are messy and the clamping of the titanium ingot is affected due to the fact that a plurality of cooling sub-tubes are tapped from the cooling main tube with the cooling main tube are effectively solved, the structure of the cooling tube 2 can keep that each cooling hole 2a on the cooling tube is equidistant from the sawing seam of the titanium ingot, and therefore the balanced cooling effect is achieved.

Preferably, the cooling pipes 2 are detachably connected to the bottom end of the cooling main pipe 1, and a plurality of adapted cooling pipes 2 are manufactured according to different external diameters of titanium ingots, and when different titanium ingots are cooled, the cooling pipes 2 with corresponding specifications can be selected.

Since the cooling tube 2 has a circular arc structure, when cooling, the cooling liquid flows out from each cooling hole 2a and then directly drops along the bottom surface of the cooling tube 2 to the two ends of the cooling tube, so as to influence the amount of cooling solution directly sprayed onto the titanium ingot by the cooling liquid at each cooling hole 2a, as shown in fig. 5-6, cooling nozzles 3 are arranged at the outer ports of each cooling hole 2a in an extending manner, and each cooling nozzle 3 is perpendicular to the outer peripheral surface of the titanium ingot. After being sprayed out from the cooling nozzle 3, the cooling liquid in the cooling pipe 2 can be directly contacted with the titanium ingot, so that the problem that the cooling liquid flows out from the cooling holes 2a and drops along the two end parts of the cooling pipe 2 to influence the liquid quantity of the cooling liquid and the cooling of the titanium ingot is solved.

Since the saw blade is usually thinner, and the saw cutting of the titanium ingot is narrower, only a small part of the cooling liquid sprayed from the plurality of cooling nozzles 3 flows into the saw cutting, saw the saw blade and the titanium ingot for cooling, and most of the cooling liquid is left along the periphery of the titanium ingot, so that the cooling of the saw blade and the titanium ingot cannot be realized, the effective cooling liquid amount in the cooling liquid output by the cooling main pipe 1 is lower, and the output power of the cooling liquid pump needs to be increased, therefore, in order to solve the problem, as shown in fig. 5-6, the cooling nozzles 3 comprise straight barrel sections 31 and flat barrel sections 32 communicated with cooling holes 2a, the outer ends of the flat barrel sections 32 are provided with cooling flat barrel sections 3a, the cooling liquid is continuously conveyed by the cooling pump in the straight barrel sections 31 dispersed into each cooling nozzle 3, the cooling liquid is sprayed out in the flat barrel sections 32 in the shape of ports, the sprayed shape is the straight barrel sections, the flowing waste of the cooling liquid on the periphery of the titanium ingot can be reduced, and meanwhile, the flat barrel sections 32 increase the width of each cooling nozzle 3 along the periphery, so that the whole cooling nozzle can realize the whole cooling effect of the cooling nozzle is realized, and the whole cooling joint effect of the cooling nozzle is realized.

In order to further reduce the flow waste of the sprayed cooling liquid on the peripheral surface of the titanium ingot, preferably, the width of the cooling flat port 3a is smaller than the width of the saw cut of the titanium ingot, so that the cooling liquid sprayed from the port of the flat port section 32 can flow into the saw cut, and the flow waste of the cooling liquid on the peripheral surface of the titanium ingot is further reduced.

The cooling liquid can have certain ejection effort after driving through the cooling liquid pump to can effectually get into and saw cut in the seam and realize the cooling, and after the cooling liquid pump drives, still can spray the cooling liquid and cause splashing through flat mouth section 32, pollute the nearly position of titanium ingot outer peripheral face and saw blade on the sawing machine, influence later cleaning, consequently, as shown in fig. 7 be provided with flexible pipe 4 between cooling main pipe 1 bottom with cooling tube 2, this flexible pipe 4 is the plastic bellows, saw cut and after inserting in the titanium ingot completely when the saw blade, move down cooling tube 2 with flexible pipe 4's regulatory action, make flat mouth section 32 of cooling nozzle 3 can imbed in saw cut the seam to can effectually avoid the cooling liquid to splash to the titanium ingot outer peripheral face and the cooling liquid waste that causes and later cleaning difficulty problem on the sawing machine body, after the cooling liquid that spouts can fully realize the cooling effect, and then reduced the working power of cooling liquid pump because the large diameter saw blade time is longer, consequently can reduce the energy consumption of cooling liquid pump.

In order to achieve a high degree of control of the lowering of the cooling pipe 2, an adjustment lever 5 is shown in fig. 7, which adjusts the distance between the cooling main pipe 1 and the cooling pipe 2. The adjusting rod 5 is provided with a vertical adjusting bar hole (not shown in the figure), and the adjusting height of the cooling pipe 2 can be locked through an adjusting screw rod fixed on the cooling pipe 2 so as to adjust the proper depth of the flat mouth section 32 of the cooling nozzle 3 to be embedded into the saw cutting seam.

The principle of the utility model is as follows: the cooling main pipe 1 of the sawing machine body is communicated with the cooling pipe 2 which is provided with an arc-shaped structure parallel to the peripheral surface of a sawed titanium ingot, cooling ports 2a are formed in the bottom surface of the cooling pipe 2 along the circumferential interval, cooling nozzles which can be embedded into sawing slits are arranged at the positions of each cooling port 2a, when the sawed titanium ingot is cooled, cooling liquid is sprayed out from the port of the flat port section 32 of each cooling nozzle 3 and can be further embedded into the sawing slits, so that the cooling effect of the cooling liquid is improved, the waste of the cooling liquid caused by the cooling liquid flowing to and splashing to the peripheral surface of the titanium ingot is reduced, and the cleaning difficulty of the cooling liquid and the working power of a cooling liquid pump are reduced.
